Cannot Install Catalina

I have a MacBook Pro (Late 2013) and I am trying to upgrade from OS 10.9 to Catalina. I downloaded the installer from the App Store, but it won't do anything when I click "install". Is there an issue with the installer?

You can try launching the installer when in Safe Boot..


Try a SafeBoot https://support.apple.com/en-us/HT201262

Takes noticeable longer to get to the login screen, does a 5-15 minute disk repair before it fully boots up, and certain system caches get cleared and rebuilt, including dynamic loader cache, etc. Login and test. Reboot and test as caches get rebuilt.


In Safe mode third party system modifications and system accelerations are disabled, it removes malware etc. . A reboot will put it back to normal mode.
